If the deposit replaces the entire word, optimize to a move.
If we're inserting to the top of the word, avoid the mask of arg2
as we'll be shifting out all of the garbage and shifting in zeros.
If the host is 32-bit, reduce a 64-bit deposit to a 32-bit deposit
when possible.

Adding an offset to a void pointer works with gcc but is not allowed
by the current C standards. With -pedantic, gcc complains:
exec-all.h:344: error: pointer of type ‘void *’ used in arithmetic
Fix this, and also replace (unsigned long) by (uintptr_t) in the same
statement.

While ALIGNADDR was implemented out-of-line, ALIGNADDRL was not
implemeneted at all. However, this is a very simple operation
so we're better off doing this inline.

This reduces the size of the individual translation blocks, since
we only emit a single call for each FOP rather than three. In
addition, clear_float_exceptions expands inline to a single byte store.

This allows a more efficient representation for 64-bit hosts.
It should be about the same for 32-bit hosts, as we can still
access the individual pieces of the double.

Begin using i64 quantities to manipulate double-precision values.
On a 64-bit host this will, for the moment, generate less efficient
code; on a 32-bit host code quality should be largely unchanged.
Code quality for 64-bit will be adjusted with a subsequent patch.

Load, store, and "create destination". This version attempts to
change the behaviour of the translator as little as possible. We
previously used cpu_tmp32 as the temporary destination, and we
continue to use that. This will eventually allow a change in
representation of the fprs.
Change the name of the cpu_fpr array to make certain that all
instances are converted.

The MinGW-w64 gcc complains about wrong parameters for
gen_helper_fpadd16_s and three other functions.
gen_helper_fpadd16_s is declared like this (hidden in lots of macros):
static inline void
gen_helper_fpadd16s(TCGv_i32 retval, TCGv_ptr arg1,
TCGv_i32 arg2, TCGv_i32 arg3);
So it looks like cpu_env should be the 2nd parameter.
Please review this patch as I have no environment to test it
(maybe the 1st parameter should be cpu_dst?).
